I'm invincible since the end of the world

Compared to the rough buildings in the periphery, which were randomly built with huge stones, the building in front of him was much more luxurious.

It was not to say that it was so magnificent, but at least it looked like a palace, and the outer wall had been processed, with many hollow carvings, making the whole building look rough and exquisite.

Lin Xinghai estimated that this should be the work of the elf zombies.

This situation made him feel a little sad.

It can be imagined that if the earth is completely occupied, all humans will be transformed into zombies in the future, and they will probably be treated as slaves.

Lin Xinghai shook his head slightly and forcibly restrained all his emotions. He had just walked around here.

Although he did not dare to use his perception to explore directly, it was no problem to just let his perception permeate the surface of his body to sense the fluctuations of his Yuanli and blood power.

No matter what kind of power it was, he could detect strong fluctuations from this building.

And in this process, he also saw many mutant zombies coming in and out. Obviously, this should be an open place.

However, the mutant zombies that can come here are at least level three or above, so the specifications are still relatively high.

Lin Xinghai took a deep breath and walked directly towards the building.

When he got closer, he saw the two big words "Tianchi" on the doorplate.

And there was a peak level four death claw standing guard by the gate.

This is almost the strongest individual below the rule realm among the mutant zombies. With it, all the zombies that come in become quite well-behaved.

And this is just the strength standing guard at the gate. You can imagine how terrible the guard force inside is.

After Lin Xinghai approached, he took out the dominoes without the other party's instructions.

The inspection here is much stricter. He was not let in directly like at the gate.

At this moment, there is a formation under his feet, which is slightly lit at this time.

The dominoes in his hand resonated with the formation below and also emitted a bright light.

Lin Xinghai estimated that this should be a means of verifying the authenticity of the dominoes.

And not only that, because he found that there was a kind of fluctuation in the dominoes, trying to resonate with him.

This situation was not expected by him, and Lin Xinghai didn't know what to do next.

But at this moment, the simulation ability of the system fluctuated slightly, and then resonated with the dominoes.

Soon the faint light of the dominoes turned green.

Roar! (Authentication passed, you can go in.)

Deathclaw roared.

Hearing this, Lin Xinghai's hanging heart was secretly put down, and at the same time he sighed that the system was awesome.

Obviously this was some kind of special detection method, and it might even be a blood test.

But even so, the system could simulate it.

It can be said that as long as Lin Xinghai did not expose his own flaws, the simulation ability of the system was 100% perfect.

He walked in steadily, and after the deathclaw shifted his sight, Lin Xinghai immediately sped up and soon saw the third-level giant arm that had just come in in front of him.

Lin Xinghai was not familiar with this place at all, so he deliberately waited for the mutant zombies to enter before he followed in.

The zombies were in front of him to set an example for him and let him know what to do.

Tianchi is different from normal buildings. After entering the gate, there is no hall or anything like that, but a long corridor.

Lin Xinghai followed the giant arm in front and soon came to the end of the corridor. Here was a fork, leading to three different directions.

The giant arm in front walked to the corridor on the left without thinking.

Lin Xinghai took two quick steps and came to the fork. Soon he saw three signs above the corridor.

They were written: Upper Tianchi, Middle Tianchi and Lower Tianchi.

The giant arm was walking in the passage of the Lower Tianchi.

Lin Xinghai thought about it and followed it.

As he moved forward, he soon saw stone doors on both sides of the corridor.

Lin Xinghai stretched out his hand and pushed, and found that these stone doors were set with formations and could not be opened directly.

However, after walking a little further, some open stone doors were found.

Lin Xinghai glanced at it and found it empty. The only special thing was that there was a huge pit in the middle.

The giant arm in front stopped at an open stone door. It took out the identity token and pressed it on the door. Soon, a formation appeared at the door.

The giant arm walked in immediately, and the door closed, blocking Lin Xinghai's sight.

But seeing this was enough for Lin Xinghai.

He immediately took out his identity token, and then followed the giant arm's example and pressed it on the same position of the stone door.

The formation on the stone door was immediately activated. In Lin Xinghai's perception, the formation of the stone door seemed to be connected to the entire building. He estimated that he might not be able to open it even with his full strength.

"It's amazing! It would be great if I could get the inheritance of the formation." Lin Xinghai whispered to himself.

According to the information he had learned, there were some formations that had enormous destructive power. If they could be deployed to guard the abyss passages, then the human army would have an easier time.

While Lin Xinghai was daydreaming, a line of corpse text appeared on the stone door: "Open the lower-level Tianchi, deduct 10 contribution points, and the remaining contribution is 125 points."

"This cost is really high!" Lin Xinghai couldn't help muttering.

You know, the one he replaced is a fourth-level mutant zombie comparable to the God and Demon Realm, but the total accumulated contribution is only more than 100 points.

In other words, even mutant zombies in the God and Demon Realm don't dare to consume this Tianchi casually.

But this also made him more excited.

Lin Xinghai immediately walked into this stone room, activated the gate of the formation, and began to close automatically.

This room was also empty, but as the door was completely closed, Lin Xinghai saw a bright red liquid began to emerge from the huge pit in the middle of the room.

Soon, the place that was originally sunken turned into a small pond, but the water in it was bright red like blood.

Looking at this scene in front of him, Lin Xinghai couldn't help but frown slightly, but he still walked over and stretched out his hand to feel it.

Soon, a surprised expression appeared on his face, "Such pure energy."

Lin Xinghai immediately tried to absorb it. Anyway, he had a system that could store and withdraw energy, so he was not afraid of any problems.

As he absorbed it, Lin Xinghai discovered the magic of the pool of water in front of him.

The energy contained in it can improve cultivation like the elixir of the God and Demon Realm, and can also improve the God and Demon Body like the original liquid of creation.

And the efficiency is extremely high, more than 10 times faster than Lin Xinghai's cultivation by swallowing elixirs.
